The Oregonian: Traffic Triples Risk of Heart Attack, Study Says

From The Oregonian:

 So, anyone with heart problems and a high-stress commute should take a hard at look at a new German study showing that traffic jams can triple your chances of a heart attack within an hour.  German researchers reported the findings at the American Heart Association's 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention last week.  They also observed small but statistically significant increases in the chance that a heart attack occurred within six hours after exposure to traffic.  So, people with elevated risks of a heart attacks should think about abandoning their cars for a bus or a bike, right?  Well, maybe. Maybe not. Riding your bike in traffic, or riding on the bus - in fact, any exposure to traffic -- threatens your heart, according to the study of more than 1,400 Germans who had heart attacks between 1999 and 2003.
